Shop Talk: Sound Like a Pro with These Proper Auto Terms – Part II

"Shop Talk," or terms used by automotive professionals, can be confusing to the average automobile owner. Even some of the most common words can be misused or confused with others if you aren't in the business. To develop good communication with your AAA Car Care Center technician, it helps to know the basics before you bring your car in for service. Sound like a Pro with these proper auto phrases. 

  • Brake Drum – A spinning “drum” that brake shoes press against in a drum brake system. This component of the braking system is often made of cast iron making it resistant to wear and able to conduct heat. When you hit the pedal, the piston pushes the brake shoes against the drum, which forces your vehicle to stop. 
  • Brake Fluid – A hydraulic fluid used to transfer force into pressure in brake systems. Brake fluid is necessary to ensure your brakes are working properly. It serves as a lubricant for all moving parts and prevents corrosion. As brake fluid ages, it doesn't work as efficiently, so it should be checked or possibly replaced during routine maintenance.
  • Tire – The engineering marvel made primarily of rubber, metal, and fabric that is mounted on a wheel. Your tires are the main thing standing between you and the road. It is important for your tires to be adequately inflated so that they will wear evenly. Rotating tires prolongs their life and can improve your vehicle's performance and fuel economy.

  • Spark Plug – A device that delivers an electrical spark into the combustion chamber of an internal combustion engine. Although small, the heat emitted from the plug is like a tiny bolt of lightning. It creates the ignition for the combustion needed to power your car's engine. Without the spark, your car won't start or run at all. Bad spark plugs can also lead to engine problems and a drop in fuel economy. Check out these 4 signs that indicate you might need new spark plugs. 
  • Master Cylinder – The control device that powers brake systems. The brake master cylinder is one of the most important parts in your car. It serves as the main valve that pushes brake fluid through the brake lines so the calipers can squeeze the pads against the rotors. You may need to replace the master cylinder if the brake warning light is on, brake fluid is leaking, or the brake pedal goes all the way to the floor when pushed.
